Steven is a young boy sent to live in the Pennsylvania countryside with his grandparents while his mother (Tara Reid, American Pie) and father work through their marital troubles. Though his grandmother (Academy/Emmy Award winner Cloris Leachman) and grandfather are happy to host him, they warn Steven not to enter the cornfields next to their house. Meanwhile, Steven hears news of the notorious Manson family and their gruesome killing spree. He develops a morbid fascination with the murderous cult and at the same time he can't help but be drawn into the mysterious cornfields. Eventually he goes against his grandparents' wishes and enters the fields -- where he finds a dead body, though no one believes him. Then, menacing noises begin haunting the family from outside at night and the two family dogs go missing. Though Steven's family tries to protect him, whatever's lurking in the fields is about to make their lives a living nightmare.
